The pipe d extends i 3 ion closet but it will be understood at upwardly through the casing c and is pr0- outset that the "ivention not limited vided with the valve 0!, It is also provided 13.0

with a lateral branch (l which extends upwardly and is topped by an air dome The pi e e is connected to the annulus a by a suite le coupling device which may be constructed as follows :--An externally threaded sleeve its closely but slidingly around the lower end of the pipe 1.! and has screwed upon its upper end a collar g with an inwardly proj(- cting flapige 9 Between the flange and the end of the sleeve thereis a rubber ring g which. when com pressed. forms a tight joint between the pipe and the sleeve The lower end of the sleeve is expanded as snown. and between it and the inner wall of the annulus or amiular flange a, is a rubber packing h which is bent outwardly so as to rest upon the top of the annular flange. A. collar It is threaded upon the sleeve and when screwed home draws the sleeve 9 up wardly so as to form a tight joint between it and the annular flange a. A. washer may be interposed between the collar h and the gasket h as illustrated. The pipe (1 is connectcd or coupled to the chamber a by a coupling similar to, only smaller in size than that just described, and as it di'il'ers in no essential respects therefrom it need not be eX- plained in detail any more than to say that IS the sleeve, 76 k the collars and It A? the rubber or packings. From this de scription it will be observed that the only visible connection between the closet and the tank and the stack, is the pipe (2 and at the same time the nature of the couplings is such as to permit of more or less adjustment of the closet bowl with relation to the tank and the apparatus therein contained. The annular soacc between the pipe (I and the pipe 6 is of course made sullicient to carry a way the air from the bowl.

The downwardly extending portion 0 of the conduit in the tank a'll'ords an overflow for the water in the tank, and the over-flowing water passes down. through the ventilating pipe 0 and through the ducts a into the bowl. By virtue of this construction, the fact that water is wasting, is quickly observed, so that the ball-cock mechanism may be repaired. it is customary in siphon closets for the wasting water to pass unobserved into the bowl through the jet duct, s.)

that the present ar angcmonthas advantages.

.llaving thus explained the nature of the invention, and described a way of construct: ing and using the same, although willnmt attempting to set forth all of the forms in which it may be made, or all of the modes oi its use, I declare that what I claim is:----

-1. The combinationv with a water-closet and a tank, of a vent pipe or conduit leading from the cl osctthrough the tank, andv a flushing pipe connecting the tank with the closet and being contained within the vent-pipe or conduit from the closet to the tank, substan tially as described.

screen 2. The combination with a water-closet and a tank, of a metallic vent-pipe or conduit leading from the closet to thetank and having a branch opening into said tankl'or the overflow of water from. said tank into the bowl through said vent pipe or conduit and a metallic flushing pipe connecting the tank with the closet and arranged within said vent pipe from the tank to the closet.

3. The combination with a tank, and awater-closet having a ventilating chamber and an inlet chamber, one superimposed directly above the other, of a metallic ventilating conduit connnunicating directly with the flush ing chamber and passing through the tank to the atmosphere, and a metallic flushing pipe communicating with the inner chamber and with the tank, said ventilating conduit completely inclosing and concealing said inlet pipe from the closet to the tank, substantially described.

4. The combination with a water-closet having a ventilating chamber communicating with the bowl and an inlet chamber arranged below the ventilating chamber and communicating with the flushing rim, a flushing-pipe passing through the ventilating chamber, a slip coupling connecting said flushing pipe to the walls of said inlet chamher, a ventilating conduit inclosing and con-' cealing the flushing pipe, and a slip-coupling connecting the ventilating pipe to the walls of the said ventilating chamber.

5. The combination with a water-closet having one or more ventilating ducts, and a tank, of a ventilating conduit leading from the closet and passing through the tank, said ventilating conduit having a branch opening into the said tank for the overflow of water from the tank into the b owl through said conduit, a flushing pipe extending from the closet to the tank within the ventilating conduit an d emerging therethrough in the tank, and valve mechanism connected to the flushing pipe and arranged in the tank substantially as described.

6. The combination with a water-closet bowl having a ventilating chamber conn nunicating with the bowl and an inlet chamber directly below the ventilating chamber and comn'mnicating with the 'llushing rim, the walls of said chambers being inwardly beveled, a llushing pipe, a ventilating pipe inclosing the flushing pipe, a sleeve having an expanded lower end clamped to the walls of each of said chambers, and slip-joints between said sleeves and said pipes respectively, substantially as described.

In testimony whereof I have afiixed my signature, in, presence of two witnesses.
